Movable Contact Holder Assembly for FAKRA Connectors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connectors do not effectively combine shielded analog signals and power for remote circuitry while adhering to FAKRA standards, and lack proper contact positioning assurance, risking circuit failure or component damage.
Innovation Solution
A contact holder assembly with a movable and fixed body portion, elastically combined by a ring, which provides high contact retention and visual, tactile, or audible indications of proper contact positioning, allowing for different types of contacts and minimal insertion effort, and compatible with FAKRA form factors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single connector combines shielded analog signal and power for remote circuitry, then functionality is improved, but compatibility with FAKRA standards deteriorates
Solution Approach 1:
The connector is divided into separate contact holder assemblies, each dedicated to specific functions (shielded analog signal in one housing, power for remote circuitry in another). This segmentation allows each assembly to be optimized for its specific function while collectively providing enhanced versatility, resolving the contradiction between functionality and standard compliance.
2Reliability
If contact retention force is increased, then connection reliability is improved, but insertion effort increases
Solution Approach 1:
The contact holder assembly incorporates a movable body portion that dynamically adjusts during insertion. The movable portion allows initial easy insertion by moving away from the fixed body portion, then provides high retention force once the contact is properly positioned, resolving the contradiction between retention strength and insertion ease.
3Manufacturing precision
If contact positioning precision is increased, then circuit reliability is improved, but device complexity increases
Solution Approach 1:
The contact holder assembly employs self-aligning features including inclined portions and indication mechanisms that automatically guide the contact into proper positioning. The movable body portion self-adjusts during insertion to ensure precise alignment, eliminating the need for complex external positioning mechanisms while maintaining high precision.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enables secure and efficient connection of both DC power and shielded analog signals within a single connector, ensuring proper contact alignment and retention with minimal effort, thus preventing circuit failures and component damage.
Implementation Method 1
a ring elastically combining the movable body portion and the fixed body portion such that the movable body portion moves away from the fixed body portion as the contact holder assembly receives a contact

AI summary
A contact holder assembly receives a contact. The contact holder assembly includes a movable body portion, a fixed body portion, and a ring elastically combining the movable body portion and the fixed body portion such that the movable body portion moves away from the fixed body portion as the contact holder assembly receives a contact. The movable body portion includes an inner surface and an inclined portion on the inner surface.
